उत्तर
Given:
Initial investment = ₹ 9000 in 3% stock at ₹ 90
Sold at ₹ 95
Reinvested in 4% stock
Income increased by ₹ 80
Nominal value = `(9000/90)xx100`
= ₹ 10,000
Income = 3% of ₹ 10,000
= ₹ 300
Proceeds = `(10000/100)xx95`
= ₹ 9500
New income = ₹ 300 + ₹ 80
= ₹ 380
Let the price of 4% stock = ₹ x
Nominal value purchased `= 9500/x xx100`
Income = `4/100xx(9500/x xx100)`
`=(4xx9500)/x`
`=38000/x = 380`
`=> x=38000/380`
= ₹ 100
